【摘要】 以固体超强酸S2O82-/ZrO2为催化剂,以没食子酸和月桂醇为原料,二氧六环作溶剂,直接酯化合成没食子酸月桂醇酯。得出最佳工艺条件为:在酸醇物质量比1∶1～1∶1.4,催化剂用量0.01g·mL-1,反应温度125℃,反应时间3h,酯化率可达85.2%。同时也确定了催化剂最佳制备条件。更多还原

【Abstract】 Gallic acid lauryl alcohol ester was synthesized from gallic acid and lauryl alcohol by direct esterification using solid super acid S₂O₈ 2-/ZrO₂ as catalyst in the solvent of dioxane.The yield could be up to 85.2% under optimum conditions as follows: the molar ratio of gallic acid to lauryl alcohol 1∶1～ 1∶1.4,the dosage of catalyst 0.01 g/mL,reaction temperature 125 ℃,reaction time 3 hours and the optimum conditions for preparing catalyst were also determined.更多还原
